Yeah, this guy is going to get murder 1 if the news reports are correct.
One of his past neighbors is going to testify that Rodriguez did the same thing with their family (Come over to complain, create a scene, pull a gun and claim he was in fear for his life). He also apparently was the only person the local firefighters union ever kicked out . They gave him the axe for being "divisive and paranoid.". According to this article, Rodriguez had engaged in similar behavior in his old neighborhood.
Additionally ABC 13 in Houston reports that the jury will not hear the testimony of a neighbor who claims that Rodriguez bragged to her that you could basically shoot anyone you wanted as long as you said you were in fear for your life.
